Ecosystem
An ecosystem (or ecological system) consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and microbes. Ecosystems are controlled by external and internal Environmental factor, factors. External factors such as climate, parent material which forms the soil and topography, control the overall structure of an ecosystem but are not themselves influe ...

Mohave Trail
The Mohave Trail was a Native American trade route between Mohave Indian villages on the Colorado River and settlements in coastal Southern California. History Starting from Mohave villages along the Colorado River in the upper Mohave Valley, the Mohave Trail ran westward between springs across the Mojave Desert, from Piute Spring to Indian Well, to Rock Springs, then to Marl Spring and Soda Spring on the west side of Soda Lake. From there the trail led to the mouth of the Mojave River southwest of Soda Lake. It then followed the river up stream, finding oases of water and vegetation where the river came to the surface at various places along its course. At what is now Summit Valley, the trail turned upward into and over the San Bernardino Mountains at Monument Peak, then descended into the San Bernardino Valley at the mouth of Cajon Canyon. Spanish and American era The Franciscan missionary Francisco Garcés was the first European to travel and report on the route i ...

Jedediah Smith
Jedediah Strong Smith (January 6, 1799 – May 27, 1831) was an American clerk, transcontinental pioneer, frontiersman, hunter, trapper, author, cartographer, mountain man and explorer of the Rocky Mountains, the Western United States, and the Southwest during the early 19th century. After 75 years of obscurity following his death, Smith was rediscovered as the American whose explorations led to the use of the -wide South Pass as the dominant point of crossing the Continental Divide for pioneers on the Oregon Trail. Coming from modest family background, Smith traveled to St. Louis and joined William H. Ashley and Andrew Henry's fur trading company in 1822. Smith led the first documented exploration from the Salt Lake frontier to the Colorado River. From there, Smith's party became the first United States citizens to cross the Mojave Desert into what is now the state of California but which at that time was part of Mexico. On the return journey, Smith and his c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alta California
Alta California ('Upper California'), also known as ('New California') among other names, was a province of New Spain, formally established in 1804. Along with the Baja California peninsula, it had previously comprised the province of , but was split off into a separate province in 1804 (named ). Following the Mexican War of Independence, it became a territory of Mexico in April 1822 and was renamed in 1824. The territory included all of the modern U.S. states of California, Nevada, and Utah, and parts of Arizona, Wyoming, Colorado, and New Mexico. In the 1836 Siete Leyes government reorganization, the two Californias were once again combined (as a single ). That change was undone in 1846, but rendered moot by the U.S. military occupation of California in the Mexican-American War. Neither Spain nor Mexico ever colonized the area beyond the southern and central coastal areas of present-day California and small areas of present-day Arizona, so they exerted no effective contro ...

Amphibian
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic ...
